Specification of Letters Patent.

Patented July 1, 1919.

Application filed March 28, 1918 Serial No. 225,272.

To all whom it may concern:

Be it known that I, HERBERT E. BRIDG- wA'rnn, citizen of the United States, and resident of Syracuse, in the county of Onondaga and State of New York, have invented certain new and useful Improvements in Type-VVriting Machines, of which the following is a specification.

l\'[y invention relates to means for guiding type bars or carriers of typewriter or like machines to a common printing center.

Diliicully has been found heretofore in providing highly efficient guiding means of the character specified. Attempts to provide means for accurately guiding the type bars usually resulted in the bars sticking in the guides, thus resulting in great annoyance to the operators and loss of much time in releasing the sticking bars, readjusting the carriage, etc. In some instances the constructions were such that very small. guiding surfaces were presented and very slight wear would soon render them inefficient. In other instances means were devised for guiding the type hars against lateral deflection but no means were provided to prevent a deflection of the type bar in the direction of its length. It has been proposed to employ roller guides to overcome some of these diflieulties, the rolling contact faces of the guides distributing the wear over greater surfaces and also rendering the bars less liable to stick in the guides. In no instance, however, so far as I am aware, have rolling guide surfaces been employed to prevent a longitudinal as well as a lateral deflection of the type bars.

One of the main objects of my invention, generally stated, is to provide simple and highly efficient type har guiding means which may be produced at small cost and by which the disadvantages pointed out above may be overcome.

To the above and other ends which will hereinafter appear my invention consists in the features of construction, arrangements of parts and combinations of devices set forth in the following description and particularly pointed out in the appended claims.

In the accompanying drawings, wherein I have shown only so much of one form of typewriting machine as may be necessary to illustrate my invention in its embodiment therein, and wherein like reference characters indicate corresponding parts in the different views,

Figure 1 is a fragmentary'side view partly in section of a type bar segment with several type bars and the type bar center guide mounted thereon.

Fig. 2 is a fragmentary rear elevation of. the same, showing but a single end type bar.

Fig. 3 is a view similar to Fig. 1, except that but one type bar is shown, and the center guide appears in side elevation, whereas the segment is shown in section.

Fig. 4 is an enlarged detail front elevation of the center guide shown attached to the segment.

Fig. 5 is a. forc-andaft vertical sectional view of the same taken on the line wa; of Fig. 4 and looking in the direction of the arrows at said line.

Fig. 6 is a rear elevation partly in section of the same, the section being taken on the line 4y of Fig. 5 and looking in the direction of the arrows at said line.

Fig. 7 is an enlarged detail fragmentary sectional view of one of the type bars at the left-hand side of the system as viewed from above when near the printing point, the section corresponding to the line z-2 in Fig. 12 and looking in the direction of the arrows at said line.

Fig. 8 is a corresponding view of the center type bar.

Fig, 9 is a corresponding view of one of the type bars at the right-hand side of the system.

Fig. 10 is a developed plan view showing the forward ends of one-half of the system of type bars.

Fig. 11 is a diagrammatic front elevation showing the two extreme side type bars and the center type bars as they appear at the printing point.

Fig. 12 is an enlarged detail diagrammatic side elevation partly in section and showing an end portion of one of the center type bars and extensions in dotted lines of the guide surfaces on the bar as seen from the side.

Fig. 13 is an enlarged detail diagrammatic top plan view showing extensions in dotted lines of the guide surfaces on two side hairs and the center bar and how such surfaces coact with the center guide.

In the present instance I have shown my invention embodied in a well-known style of front strike ty ie\vr'iting machine. It should be understood, however, that the invention may be incorporated in various styles of iypcwriting or like machines and is in no sense ri'istricted to its use in the machine of the character shown.

In the present instance e series of segi nentally arranged type bars 1 are mounted to move upwardly and rearwardly to printing position and to strike against the front face of the platen 2 mounted in a. carriage (not shown) to travel from side to side ofthe ma chine over the to plate thereof. The type bars are mounte on a pivot wire 3 carried by a type bar segment 4:. the heels of the type bars working in guide slots 5 which extend through the lower edge of the seg ment. The type bars as they approach the sides of the system are bent laterally at the end portions thereof as best shown in Fig. 10 the line of the bend in each bar being indicated at 6. From an inspection of Figs. 1 and 11 it will be understood that the body portions of the type bars converge at a. point roincidont with the lines (3 of the bends therein when the type bars are in printing position, the printing point 7 being above and not at the point of convergence of the bars. The construction is such therefore that end portions 8 of all of the type bars, which carry the type blocks 9, are adapted to be brought to the same vertical plans when the bars are in the printing position as will be understood from a consideration of Fig. 11. There is nothing unusual in this construction but it is pointed out in detail herein in order that there may be a better appreciation of What is to follow. 1

Any suitable means may be employed for actuating the type bars and for effecting a relative ease shifting movement between the platen and type bars. I

A center guidefwhioh is designated as a whole by the'reference'numera-l 10, is fiiied in the. path of all the type bars and c'oeots therewith at the pprtion 8 of'eacli bar which is beyond the line 6 thereof, or beyond that portion of the bar which is coincident with the point of convergence of the bars. With in the broader aspects of my invention this center guide may be variously formed, many widely divergent forms ofconstrurtion having been devised by me but it will sui'fice to describe in detail the form shown in the abrompanying draw'ngs.

In the present instance roller guide surfaces which co-act with each type bar are formed on a single center guide roller, though from certain as sets of my invention it is not necessary that such s qrfaces be formed on a single guide roller.

The center gu'ide' roller is designated as a whole by the reference numeral 1, and is respectively.

formed in the present instance with trunnion-like cone pivots 12 at the ends thereof. These pivots bear against the rounded cor- 11ers 13 of bearings formed in two bracketlike su porting arms H- and 15 between which he roller is received and by which it is supported horixontally in position. The axis of the roller therefore extends transyersely of each type bar when the latter is in the printing position. The arms 14 and i5 constitute members of a twopart bearing or support, the members of which are united for relative adjustment and which are pro vided with means whereby the support in its turn may be rigidly connected to a relatively fixed support, such as the type bar segment 4. Thus, from an inspection of Figs. 4, 5 and 6 it will be seen that the member 15 has two semi-cylindrical bear ing members 16 which are received in corres onding seats 17 in the member It. This one ice the member 15 to receive a slight swinging or pivotal movement on the mene her 14, the inner face of the part 15 be ing inclined in opposite directions, as indi cated at 18, to facilitate such movement. The effect of iis movement of the member 15 is to bring e u per ends of the two arms and ,the bearings therein closer together or to move them further apart as the case may be. This relative adjustment between the bearing arms enables the roller to be properly aintained in its centered position, free fnom y ost motion at the bearings and to take up any snch lost motion which might occur as a result of wear on the bearings. Means for uniting the two members 14 and 15 and for eifeeting the above described adjustment will now be set forth.

A centrally disposed headed screw 19 extends through transverse openings 20 and 21 in the stems of the members 15 and 14 The Xis of the screw 19 passes through the axis of the bearings 16 so as to enable an adjustment of the meml)??? 15 to be effected. It will be observed moreover that the walls of the openin 20 s ope outwardly fro the screw and from e inner face of t e member 15, so that the screw 1-9 passes freely through the opening 20 and when backed up offers no obstruction to the above described adjustment of the member 15. screw 19 passes transversely through be members 14 an 15 and centrall 1 between the bearings 16 and seats 17 and is threaded into the openmg 21 wh ch is ripped to receive it. Above and below the screw 1.9 are screws 22 and 23 r spectiyely. These last mentioned screws are received in tapped openings in the member 15 and bear at their 1 ends egemst the 1 per face ,of the mom er 14,, a ove an the fithervgfilow the pwotal axis of the member 15 en the SQI'BW 19 is loosened slightly a backing-up of the screw 22 and a threading in of the screw 23 will bring the bearings 13 of the roller closer together, whereas a reversal in the movement of the screws 22 and 23 causes a relative movement of the bearings 13 away from each other. After the desired adjustment has been attained the screw 19 may be tightened and the parts will be firmly held in such position, all three screws contributing to this end. The stem of the member 14 is extended below the member 15 and is provided with openings to receive headed screws 24, the stems of which pass freely therethrough and engage at their threaded ends in tapped openings of the type bar segment 4, or some other suitable point of support.

The guide roller 11 in the present in stance is formed with a substantially V- shaped peripheral groove 25, the side walls of which form oppositely inclined guide surfaces 26 with which corresponding guide surfaces on each type bar co-act. Thus, it will be seen that each type bar is formed with a transverse slot 27 in the front edge of the portion 8 thereof. This slot is open at the forward end, or at the front edge of the bar, and extends transversely of the bar from side to side thereof. The wall of the slot nearest the end of the bar is formed with oppositely inclined guide surfaces 28, which match the guide surfaces 26 on the roller 11 in a line contact with the latter, as shown in Fig. 6. The opposite wall of the slot 27 also is formed with oppositely inclined guide surfaces 29, which likewise match in a line contact with the guide surfaces 26 on the guide roller. From an inspection of Figs. 6 and 12 it will be understood that the guide surfaces 28 and 29 on each type bar coact with the guide roller on opposite sides of the pivotal center thereof, thus preventing displacement of the bar relatively to the guide in up and down di rection or longitudinally of the type bar, whereas the guide surfaces 26 engage each type bar on opposite sides thereof and prevent any lateral defiection of the bar. Each bar therefore has an interlocking engagement with the guide roller and is guided against deflection in two directions at right angles to each other, and is compelled to move in a true course to the printing point.

It will be seen that the surfaces 28 and 29 engage the roller and remain in engagement therewith with a line contact at four points throughout a considerable portion of the final movement of the type bar to the printing position and efficiently and accurately guide each bar in a like manner to the printing position.

In order to have the guide surfaces on each type bar co-act with the guide roller in the'manner described the guide surface on each bar is formed on an arc of which the pivot of the type bar is the center. This I have attempted to illustrate in Figs. 7, 8, 9, 12 and 13. While these views are diagrammatic in character, and the proportions may not be entirely accurate, they will nevertheless serve to illustrate the point in question. Referring first to Fig. 12 it will be understood that the type bar illustrated. is supposed to be one near the center of the system. It will be observed from the dotted lines extending from the surfaces 28 and 29 that each of these surfaces is formed as an arc, the center of which is the pivotal center of the type bar shown. These surfaces are not alike on any two type bars. They differ as the angular relation of each type bar in the system differs from that of all others. Thus, in Fig. 13 I have attempted to show in dotted lines an extension of the guide surfaces 29 of, say, the extreme side type bars and the center bar, as the parts are viewed from above. Assuming for the moment that the type bar shown in Fig. 12 is the center bar, and is the same bar that is shown at the center in Fig. 13, then the surfaces 29 would be formed as represented in Figs. 8, 12 and 13 in the arcs shown by the dotted line projections of said surfaces in the two last mentioned figures. As we approach either side of the system of type bars from the center, however, the arc-like formation of a guide surface on each type bar becomes more inclined, the plane thereof conforming to the angular position of the type bar in the system. This I have attempted to show in Fig. 13 in which it will be seen that each of the two extreme type bars of the system as it swings in from a side of the segment. has the guide surface 29 formed somewhat as I have attempted to illustrate it by dotted lines in Fig. 13. In every instance, however. each of the surfaces 28 and 29 on a type bar. no matter where it may be situated in the system, will be formed on an arc of which the pivot of the type bar is the center. But the relation of the guide surfaces on each type bar to the bar on which they are formed, will vary throughout the system.

This I have attempted to illustrate by the exaggerated showing in Figs. 7, 8 and 9 in which the showing corresponds to a section of the bar taken on the line z-z of Fig. 12 and looking in the direction of the arrows at said line. Moreover, each of Figs. 7. 8 and 9 shows a bar as seen from above and as it would appear in the printing position.--Fig. 7 may be taken to represent the extreme left-hand bar; Fig. 8 the center bar; and Fig. 9. the extreme right-hand bar. These bars may be said to represent the extreme differences in the relation of the guide surfaces on the type bars. The inclination of the planes of the arcs on which the surfaces are formed will be gradually less from the sides of the system to the center where the arc is in a vertical plane as indicated in Figs. 8,, 12 and t3, and an posing for the moment the bar shown in ig. 12 to be the center bar. With the guiding surfaces on the type bars formed in this manner such surfaces are capable of accurately .co6peratlug with the center guide to properly direct each bar to the printing position without undue friction or cramping between any type bar and the center guide and without liability of any of the bars sticking in the guide. From an inspection orf Fig. 6 it will be seen that it is only the guide surfaces 28 and 29 on each *bar that co-aot with the roller, thesurfaces 27 on each bar being maintained free from contact with the guide roller at all times.

The use of efficient type bar guiding means of the character shown and described herein is rendered possible by my invention of a process and machine by which the guide surfaces on the type bars are formed and which constitute the subject-matter of a separate application Serial No. 2322*? filed by me on the 3rd day of May, 1918. By such process and machine the guide surfaces 011 each type bar are cut or formed while the.

type bar describes a. movement. corresponding to its printing movement in the typewriting machine and by a tool or cutter which has surfaces that correspond in form and location to the guide surfaces on the center guide. It will be readily understood therefore that while the relation of the guide surfaces on each type bar dilfer from those of every other bar, nevertheless, these guide surfaces may be formed in a simple manner with great accuracy and that each type bar may be directed with deadly accuracy to the printing point.

Moreover, the construction provides rolling guide surfaces which reduce the liability of the type bars to Stick in the guide and distribute the wear on the center guide around the entire surface of each guide face 26, different portions of the surfaces 26 be ing resented for use at successive operations of t e type bars. On th other hand the wear on the type bars is of course distributed between all of the type bars of the system, or say, some forty-two bars, and the character of the guide surfaces on each bar is such that the wear is distributed throughout the entire extent of each guide surface 28 and 29 notwithstanding that each at a. given instant receives only a line contact on the roller. While each bar is efi'ectively guided to the printing position there is nevertheless little resistance offered by the center guide to the printing movement of each bar, and little liability of the bars to stick in the guide.

So far as I am aware I am the first to provide a center guide equipped with roll- 66 inc guide surfaces which coast With a tape mosses carrier to guide and prevent a deflection thereof in two directions at right angles t each .other.

ne of the characteristics of such a construction is the provision of .guide surfaces on thetype bars of such a character that the relation of such surfaces on each bar shall be different from that of every other bar of the system. Notwithstanding this the guide surface on each bar is formed on an arc the center of which is the pivot of the but. I believe that I am the first to provide such a construction and the first to provide means whereby .the ado. tion of such a construction is rendered .possi le-or feasible. It should be understood therefore that from the broader aspects of my invention the construction shown illustrates but one of the many forms in which my invention may be clothed and that widely divergent changes may be made within the scope of my invention.
